Fill just one tank and have a transfer pump/hose?
When you are coastal cruising do you perhaps just use one tank so that the WM gets regular use and leave the other empty?
transfer or even wash down, has anyone added a "garden hose" connection to the boats freshwater system?
We have 2- 110 gallon potable water tanks
plumbed as Tellie describes in his response
In addition, we terminate those two tank vents at [into] the galley
sink [after a loop high above waterline so the tanks can't empty into the sink while heeled...]
This way we have a visual when a tank is full.
Additionally, the two vent lines can be connected together by opening a ball valve [normal operating position] that joins the two low, under the galley
sink. This acts as an overflow manifold to fill the lower level tank when the one being filled is full. Close that interconnection valve, and the tanks fill independently. This is handy when underway and running the water maker, or when filling from a shore supply. [Even though each tanks has its own deck
Once water is flowing from the tank vent fitting into the galley sink, both tanks are full.
wash down faucets: We have two (bow and stern) plumbed together. There is a Y-valve to select between raw and fresh water [which also has a check valve before the Y...] That way we can blast away with raw water
on a dirty job (e.g., cleaning anchor
chain as it is being hoisted) and rinse with fresh as needed. (e.g., We rinse the chain pile after it is in the locker...) Likewise for dirty deck jobs, fish cleaning
Both heads are also plumbed for fresh or raw water
flushing- also eminently worthwhile.
